Appendix
The following chapter shows the various
valve technologies based on exemplary
illustrations.
10.1.1
A-/B Valve technology
In A/B valve technology,
several riser branches or
distribution lines are connected
to a common flushing line.
Here, one A valve and the B
valve are successively opened
and closed together. This
guarantees that there is no
idling in the flushing lines and
there is no water exchange
between the pipelines to be
flushed.
Example of a flushing process:
A1 and B1 open in accordance
with the specifications, A1 and
B1 close
A2 and B1 open in accordance
with the specifications, A2 and
B1 close
A3 and B1 open in accordance
with the specifications, A3 and
B1 close
A4 and B1 open in accordance
with the specifications, A4 and
B1 close
Please note:
If valve A1 is flushing, the
pending flushing processes of
other valves are blocked. With
temperature flushing, these
are
then
carried
out
successively by the system.
